Linear OOA(4¹⁷¹, 89, F₄, 2, 124) (dual of [(89, 2), 7, 125]-NRT-code), using juxtaposition based on

linear OOA(4³⁵, 21, F₄, 2, 28) (dual of [(21, 2), 7, 29]-NRT-code), using
- extended algebraic-geometric NRT-code AG_e(2;F,13P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, using
  - an explicitly constructive algebraic function field [i]
linear OOA(4¹²⁹, 68, F₄, 2, 95) (dual of [(68, 2), 7, 96]-NRT-code), using
- generalized (u,Â u+v)-construction [i] based on
  1. linear OOA(4²⁸, 17, F₄, 2, 23) (dual of [(17, 2), 6, 24]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,10P) [i] based on function field F/F₄ with g(F) = 5 and N(F) ≥ 17, using
      - an explicitly constructive algebraic function field [i]
  2. linear OOA(4³³, 17, F₄, 2, 31) (dual of [(17, 2), 1, 32]-NRT-code), using
    - strength reduction [i] based on linear OOA(4³³, 17, F₄, 2, 33) (dual of [(17, 2), 1, 34]-NRT-code), using
      - dual of repetition NRT-code with length 17 [i]
  3. linear OOA(4³⁴, 17, F₄, 2, 34) (dual of [(17, 2), 0, 35]-NRT-code), using
    - complete OOA / dual of NRT-code with only one code word [i]
